Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a cell has a concentration of 15% salt solution on the inside and the environment is 12% on the outside, what type of solution is the environment?
A
Hypotonic
B
Hypertonic
C
Isotonic
Explanation: 

Detailed explanation-1: -The salt water is a hypertonic solution, thus water will move out of the cell. As water moves out of the cells there is a loss of turgor pressure and the plasma membranes detach from the cell walls as the cells shrink.

Detailed explanation-2: -Know your tonicity Hypotonic has a lower concentration of fluid, sugars and salt than blood. Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood.

Detailed explanation-3: -What will happen to a plant cell that has a 15% salt concentration when it is sout placed into a solution containing a 4% salt concentration? a 41. water 96%-Water will move out of the plant cell, causing it to shrivel.

Detailed explanation-4: -For example, a solution containing 10% salt is hypertonic.
